My BIL smokes and when my wife goes to see her sister she comes home and everything reeks of smoke. It just about knocks me over when she walks into the house and opens up her bags. Even the clothes that she did not get out of the suitcase stink up the house so we have to wash everything that she took. He is the only one in the family that has a bad habit left all the others passed away from lung cancer and heart attacks. :roll:
All I know is if you do not smoke you can pick up on the lingering smells very quickly.
